Hello! I haven’t spent time with the MedBridge or Shepherd materials in order to maintain the integrity of the NCS Advantage (I don’t want to accidentally steal anyone’s ideas!), so I can’t say how their exams compare to the NCS Advantage.
I can say that average scores for the NCS Advantage exams are 60-70% on the first attempt. With repeated attempts of the same exam, average scores tend to increase to the 75-85% range.
Over 98% of our participants report passing their NCS exam, so it sounds like you are on track to pass your exam with your NCS Advantage scores! 🙂
